Investigation of composition of the volatile oil and biological activity of fruits from

Smirnovia iranica Sabeti is one of the plant species which is growing wild in central desert areas of Iran. The current research was carried out on determination of volatile components and biological activity of fruits from Smirnovia iranica Sabeti. Results from GC-Ms analysis revealed 37 identified components with benzene, 1-methoxy-4-(1- propenyl) (13.30%), β-Ionone (9.91%) and nonadecane (9.10%) as the major components. Evaluation of antimicrobial activity via disc diffusion assay showed that Salmonella paratyphi-A serotypeis and Staphylococcus epidermidis sensitive to the methanol extract of fruits of S. iranica. Measuring antioxidant activity via DPPH free radical scavenging activity assay exhibited very high activity (IC50=0.32 μg/ml) which was higher than that of BHT standard antioxidant.
